Grafting Eggplant Heavy Stem Base Disease

Recently, many vegetable growers who have planted eggplant have reported to reporters that eggplant grafting has now prevented verticillium wilt and blight, but it is susceptible to disease caused by grafted eggplant stalks, which affects the growth of eggplant and causes serious death of eggplant. Tree. Therefore, vegetable farmers should pay attention to the protection of the stems of grafted eggplants to prevent the occurrence of diseases.

The marrying interface is closer to the ground, and the vegetable farmer sometimes buries the marrying interface during the operation, which results in the vulnerability of the marrying interface to epidemics, stem rot, and the like. The typical symptom of the disease is that the base of the stem on the upper and lower sides of the mating interface is immersed in water at the early stage of disease, and gradually rots, turns black, and then collapses, resulting in dead trees in severe cases; while in the early stage of the stem rot, depression occurs on one side of the stem base. The black-brown small spot, with the development of the disease spots, formed a fusiform or strip-shaped lesion, and the diseased spot caused one dead tree after one week. For the disease, vegetable farmers can use 72.2% Prec 600 times or Anke 1000 times, etc. for spray irrigation and control; stem rot can be used 20% methyl-toxins 1000 times spray irrigation control. For disease-free plants, vegetable farmers can use chlorothalonil to spread stalks to prevent the occurrence of these diseases. At the same time, in daily management, they should pay attention to the interface of the graft and not contact with the soil to prevent the infection of these two diseases.

When the air humidity in the shed is relatively high, dew condensation will occur at the marrying interface of the eggplant, which will create conditions for the infection of bacterial diseases, resulting in rot in the base of the stem at the grafted interface, and overflowing of the bacterium. The farmers can prevent the bacterial diseases by covering the mulch below the grafting interface, thereby reducing the air humidity at the marrying interface, keeping the epidermis dry at the grafted interface, and reducing the infection of bacterial diseases; the vegetable farmers can also use 50% DT500. Double spray prevention, the focus of spray graft interface.

Astragalus Membranaceus, also known as Mianqi. Herbs perennial, 50-100 cm tall. The main roots are thick, woody, often branched and gray-white.
